1. A roller spinning tool comprising:

  • a handle means for being rotated, the handle means comprises an elongated cylindrical handle member having respectively opposed upper and lower ends, the elongated cylindrical handle member being shaped so to define a cylindrical outer surface having a constant radius or curvature as well as a constant diameter along a longitudinal length thereof to permit placement and rotation of the cylindrical handle member between opposed palms of a pair of human hands;

    a central engaging means extending from the handle means and being axially aligned therewith for engaging a center of a roller to effect rotation of the roller within a solvent, the central engaging means comprises a conical neck extending from the lower end of the elongated cylindrical handle and being coaxially aligned therewith, the conical neck being of a first diameter equal to a diameter of the elongated cylindrical handle member at the lower end thereof and tapering to a second diameter spaced from the lower end of the elongated cylindrical handle member, wherein the first diameter is substantially greater than the second diameter, the central engaging means further comprises a tapered gripping cone extending from the conical neck and being coaxially aligned therewith, the tapered gripping cone being of the second diameter at an intersection of the conical neck with the tapered gripping cone and tapering to a third diameter spaced from the conical neck, wherein the third diameter is substantially less than the second diameter so as to define a tapered conical shape of the gripping cone, the conical neck tapers from the first diameter to the second diameter over a first longitudinal length, with the tapered gripping cone tapering from the second diameter to the third diameter over a second longitudinal length and a difference between the second longitudinal length is substantially greater than the first longitudinal length and a difference between the first diameter and the second diameter is equal to a difference between the second diameter and the third diameter such that a slope of the side wall of the conical neck is substantially greater than a slope of the side wall of the tapered gripping cone relative to a longitudinal axis of the roller spinning tool, the central engaging means further comprises an elongated cylindrical engaging member projecting in an axially aligned manner from the tapered gripping cone, the elongated cylindrical engaging member being of the third diameter and of a constant diameter along a longitudinal length thereof.
